ELl J. MANVILLE, OF WATERBURY, CONNECTICUT. Lette/rs Patent No. 87,182, dated Februa/ry 23, 1869.

' IMPROVEMENT IN FL'TINGMACHINES.

The Schedule referred to in these Letters Patent and making pani of the same.

To all whom it may concern.

Be it known that I, ELI J. MANVILLE, of Waterbury, in the county of New Haven, and State of Connecticut, have invented and made 'a certain new and useful Improvement in Fluting-Machines; and I do hereby decla-re the following to be a full, clear, and exact description of the said invention, reference being had to the annexed drawing, making part of this specification, wherein- Figure l is a vertical section of the standard, transversely of the roller-shafts, and

Figure 2 is a plan ofthe machine complete.

Similar partsare denoted by like letters.

This machine is constructed so that the rollers can be opened with facility, and any desired amount of yielding pressure applied to keep the rollers in contact.

My invention consists in a hollow cylindrical standard, carrying a ling-collar, to which the bearings for the shaft of the lower roller are connected, and also a lever that operates upon a cylinder sliding upon said standand, and carrying the bearings for the upper rollershaft. v

The pressure to keep the tinted rollers together is obtained from a spring within the hollow standard, connected by a rod to the sliding cylinder ofthe upper roller, which rod is adj ust-able to vary the spring-pressure.

In the drawing- ,c is the hollow standard, rising vertically frornthe flaring base b, that sustains the same.

c is a collar around the lower part of the standard a, kept in place by a set-screw, 2, or other device, and this collar c carries, or is formed with the bearings d d, for the shaft c, upon one end of which is the crank f, for turning the rollers, and on the other end is the ordinary dating-roller g, with an opening at the end, for the introduction of a heater.

The sliding cylinder his fitted upon the upper part I ofthe standard a., and provided, with the bearings k, for the shaft Z ofthe upper roller m.

The cylinder It terminates with a dome, throughwhich passes the rod 'i to the spring n, in the standard-base b.

This spring n may be helical. I have, however, shown a plate, or elliptical spring. A

The nut o can be turned, to increase orlessen the pressure of the spring on the rollers.

Upon one side of the `collar c are jaws p, carrying the lever q, that serves to lift the cylinder h, and separate the rollers, for introducing or withdrawing the article to be fluted.

By allowing the end of the lever q to enter a notch in the lower end of the cylinder h, the parts are prevented from turning around laterally.

This fluting-machine is very strong and durable, and l can be constructed with great facility and cheapness, as almost all the iinishing can be done in a lathe.

What I claim, and desire to secure by Letters Patent, is

The hollow standard @carrying the collar c and .bearings for the shaft of the lower roller, in combination with the sliding cylinderh, carrying the upper roller, and a yielding pressure for keeping the 'lutingrollers toward each other, substantially as set forth.

In witness whereof', I have hereunto set my signature, this 23d day of November, 1868.
